Alright, the poster on Arnies measured the location of the bushing(~5mm in from the front), which is different from SD's, but its about 10 thou(of an inch) off from what I measured the TM 1911's to be. Consider the small variance in measurement from 2 people I am guessing it uses the TM 1911's dimension. Which means PDI's bushing, TM 1911's stock bushing, or possibly Nova's bushing will fit these AS slide to build 1911-style barrel setup...
